Assessment Studies

The NGS is subject to the Ontario Environmental Assessment Act and requires an Environmental Assessment be undertaken in accordance with Regulation 116/01, including the Ministry of the Environment’s “Guide to Environmental Assessment Requirements for Electricity Projects.” The Environmental Screening/Review Process under the Guide has two possible stages – the Screening stage and the Environmental Review stage. TransCanada has chosen to undertake the comprehensive Environmental Review.

Throughout 2012 and 2013, TransCanada initiated field work and associated studies to form the basis of the Environmental Review Report (ERR). The ERR identifies any potential effects on the environment and surrounding communities. TransCanada studied air quality and noise, archaeological and heritage resources, human health, socio-economics, terrestrial and aquatic environment.

In October 2014, TransCanada received confirmation from the Minister of the Environment and Climate Change that the Environmental Review Report (ERR) was found complete; this was followed with the receipt of the required Environmental Compliance Approvals (ECA) in November 2014. In early December, TransCanada purchased the property from Ontario Power Generation. NGS is located adjacent to the existing Ontario Power Generation Lennox Generating Station site, in the southern portion of the Town of Greater Napanee.

Key findings from the ERR

The results of the studies undertaken for the project indicate that the NGS will not have significant net environmental effects, both during construction and operation.

Study results indicate that the NGS will have little or no effect on the environment and surrounding community during construction and operation.

Modelling results, including those related to air quality and human health are within or below allowable limits set by regulatory requirements.

Water needs and evaporative losses are relatively small and will not significantly affect water resources, natural resources or climate.

The final NGS Environmental Review Report (ERR) was submitted to the Ministry of the Environment (MOE) on January 21, 2014, followed by 30-day public review period.

About Napanee Generating Station

The proposed Napanee Generating Station is a 900-megawatt (MW), combined cycle, natural gas-fuelled electricity generating station located in the Town of Greater Napanee, County of Lennox and Addington, in Ontario.

The Napanee Generating Station will be designed as a flexible system resource able to be started and stopped daily and to vary its output to bridge the gap between Ontario’s electricity demand and the other available generating resources.
